At some point in this discussion you almost have to bring up battery pack capacity, because you are sooner or later gonna be running that servo with less than full voltage, and that's when you might 'feel' a difference in servo performance. A stronger/faster servo might still give good results with a less than full charge pack during a long race. So if you don't have the best battery, you will notice it more with a slower/weaker servo, as it's performance will suffer more/sooner along with voltage drop in the pack. Y/N?

Mich, insert Helotes pitch here (.....).
